Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Magnetically sweeping the separatrix along the divertor plate is proposed to accommodate higher heat loads or to reduce the maximum armor/coating surface temperature for a given heat flux distribution. During the sweeping, each position on the divertor plate will experience periodic heat and particle flux variations. The magnitude of these variations with time will depend on the location as well as on the time shape of the sweeping wave. Consequently, the shape of the sweeping pulse and the sweeping frequency will determine the maximum surface temperature as well as the spatial distribution of the temperature along the sweeping distance. Sweeping is also expected to increase the lifetime due to reduction in both physical sputtering and chemical and radiation enhanced erosion for materials such as graphite or carbon composites.
